Encryption is widely used today because it is said to be the most effective way to achieve data security ("Encryption”). Encryption converts data into a secret code so that it can only be read by someone who has the right encryption key to unscramble it. The earliest known encryption method was created in 60BC and was called the Caesar cipher, where Julius Caesar is said to have used this method to send coded messages to his generals in the field (Hall, 84). Over the past few centuries, encryption has strongly developed, and new systems have been created. There are two important fundamental components to encryption, a key and an algorithm. The key is a mathematical value that the sender selects and the algorithm is the method of shifting each letter in the message to the number of positions that the key value specifies (Hall, 84). The receiver of the cipher text message then reverses the process to decode the...
